Mass of car, m = 1500 kg
velocity, v = 60 km/h = 60 \times \frac{5}{18}=16.67\ ms^{-1}

Kinetic energy possessed by the car =  \frac{1}{2} mv² 
⇒ KE =  \frac{1}{2} \times 1500 \times 16.67^2=208416.7\ J=208.4\ kJ

To stop the car, we have to make the KE of car 0. So the work need to be done is 204.4 kJ.
